The product we are reviewing today is the “AirGradient ONE” air quality monitor kit which is an updated version of the earlier AirGradient air quality monitor. The device is equipped with sensors from Sensirion and Plantower, allowing it to measure many air quality parameters such as CO2, PM2.5, TVOCs, NOx, temperature, and humidity. It is an indoor air quality monitor that is both open-source software and open hardware. This means that the Arduino source code, schematic diagrams, PCB, and 3D models of the enclosure are available to developers. AirGradient ONE DIY Kit Unboxing The device was packaged within a cardboard box, with a greeting card from the manufacturer. The card features a QR code linking to a webpage with the installation guide. Since I requested the Kit version (there’s also a fully assembled model), some sensors were not pre-assembled and they were well-packaged in separate seals. The main PCB was [...]

Espressif Systems has now released an alpha version of ESP32 Arduino Core 3.0.0 enabling the new ESP32-C6 and ESP32-H2 targets to be programmed with the Arduino IDE, and including a number of new features made possible by the ESP-IDF 5.1 SDK. Announced in 2021, the ESP32-C6 WiFi 6, Bluetooth 5 LE, and 802.15.4 wireless MCU became available in modules and devkits at the beginning of this year, but so far they could only be programmed with the latest version (5.1) of the ESP-IDF framework, and so was the new ESP32-H2 Bluetooth 5.2 and 802.15.4 (Zigbee/Thread) MCU. But fans of Arduino programming can now rejoice as an alpha version of ESP32 Arduino Core 3.0.0 brings support for the new microcontroller, and a stable release is planned for December 2023. But as you can probably imagine ESP32 Arduino Core 3.0.0 will also bring lots of other changes since the ESP32 Arduino Core [...]

Z-Wave.Me has sent us a couple of Smart Home devices based on Z-Wave technology for review, namely the RaZberry 7 Pro Raspberry Pi HAT and the Z-Uno2 board. The Swiss company has primarily developed Z-Wave products for years and is a member of the Z-Wave Alliance. For those who are concerned about the issues of signal interference in the 2.4GHz range (WiFi, Zigbee, Bluetooth, and Thread), Z-Wave technology is an excellent choice because it operates on a less congested frequency range of 800-900MHz and the technology has been around for more than 20 years, resulting in a wide variety of Z-Wave devices available in the market, and they can work well together across different brands due to a proper certification process which is another advantage when compared to other protocols. The two devices we received are RaZberry 7 Pro, which is a shield that plugs into the 40-pin GPIO header [...]

Last May, SparkFun introduced the “Datalogger IoT – 9DoF” no-code platform with support for over 50 Qwiic sensor modules and a built-in 9-axis IMU sensor and magnetometer. Taking into consideration that some users may not make use of the built-in sensors, the company decided to launch a cheaper version called the “DataLogger IoT” that can still get data from Qwiic sensor and GPS modules without any programming thanks to the “no-code” Arduino firmware preloaded on the ESP32-WROOM-32E module. SparkFun DataLogger IoT specifications: Wireless module – ESP32-WROOM-32E with: ESP32 dual-core microcontroller 4MB flash 2.4 GHz WiFi and Bluetooth LE connectivity, built-in PCB antenna Storage – MicroSD card slot USB – 1x USB Type-C port for power and configuration via CH340C Expansion – 2x Qwicc I2C connectors for sensors and/or GPS module Misc Boot and Reset buttons Status and charging LED, WS2812 RGB LED Jumpers to enable/disable LEDs, I2C pull-up resistors, and [...]

Our four-legged friends don’t walk on tarmac the same way as they do on ice or sand as they can see and feel the floor with their eyes and nerve endings and adapt accordingly. The TRACEPaw open-source project, which stands for “Terrain Recognition And Contact force Estimation through Sensorized Legged Robot Paw“, aims to bring the same capabilities to legged robots. Autonomous Robots Lab achieves this through the Arduino Nicla Vision board leveraging its camera and microphone to run machine learning models on the STM32H7 Cortex-M7 microcontroller in order to determine the type of terrain and estimate the force exercized on the leg. But the camera is apparently not used to look at the terrain, but instead, at the deformation of the silicone hemisphere – made of “Dragon Skin” – at the end of the leg to estimate 3D force vectors, while the microphone is used to recognize terrain types [...]

In this guide, we’ll explain how to set up a private LoRaWAN network using the Raspberry Pi CM4-based RAKwireless’ WisGate Connect gateway and Docker or Portainer to install NodeRED, InfluxDB, Grafana, and other packages required to configure our gateway. The WisGate Connect is quite a versatile gateway with Gigabit and 2.5Gbps Ethernet plus several optional wireless connectivity options such as LoRaWAN, 4G LTE, 5G, WiFi 6, Zigbee, WiFi HaLoW, and more that can be added through Mini PCIe or M.2 sockets, expansion through WisBlock IO connectors and a 40-pin Raspberry Pi HAT connector. We’ll start by looking at the gateway features in detail, but if you already know all that, you can jump to the private LoRaWAN network configuration section. WisGate Connect unboxing, specifications, and teardown RAKwireless sent us a model with a Raspberry Pi CM4 equipped with 4 GB of RAM and 32 GB of eMMC memory, GPS and [...]

Raspberry Pi Pico to Arduino Uno adapter relies on “FlexyPins” for castellated holes

Desc:

Solder Party’s “Raspberry Pi Pico to Uno FlexyPin Adapter” transforms the Raspberry Pi Pico into an Arduino UNO without soldering the board directly or using headers, but instead relying on FlexyPins flexible pins to attach the Pico board to the adapter using its castellated holes. The end result is basically the same as for the WisdPi ArduPico board, except the Raspberry Pi Pico is soldered to the main PCB on the latter, but it can be easily removed from the Solder Party’s Uno adapter board to be replaced with another compatible model, e.g. Raspberry Pi Pico vs Pico W. The FlexyPins can be used with any board or module with castellated holes, but it’s obviously especially useful for castellated modules without through holes, for example, to easily program a bunch of ESP32 modules. You’ll first need to get a few FlexyPins as shown below. Then solder them to a compatible [...]

ArtronShop RP2 Nano board features the Raspberry Pi RP2040 microcontroller in the Arduino Nano form factor in a way that’s much cheaper than the official Arduino Nano RP2040 Connect board. That’s possible because Thailand-based AtronShop did not include all the bells and whistles such as WiFi and Bluetooth connectivity, sensors, and used a smaller flash. So the RP2 Nano basically offers the same I/Os and features as the Arduino Nano, but the Microchip ATmega328 8-bit AVR microcontroller gives place to the more powerful Raspberry Pi RP2040 dual-core Cortex-M0+ MCU plus 2MB flash, and the board also adds an extra Grove connector for expansion.
